The following issue has been raised (e.g. [1]) on ws-arch: is there one
and only one ultimate receiver, or can there be several ultimate
receivers for the same message?
The issue is that multicast bindings, for example, may be prohibited if
there is only one single ultimate receiver.
Currently, Part 1 specifies there can only be ONE ultimate receiver (THE
ultimate receiver). An earlier version of Part 1 used to allow multiple
receivers (AN ultimate receiver), as per the resolution to issue 103 [2].
It appears that when the resolution to issue 103 was implemented, not
all occurences of "THE" were changes to "AN", and that an (unfortunate)
editorial sanity check later replaced all instances of "AN" to "THE",
instead of the contrary.
We have two options at this stage:
1) Go with whatever is in Part 1 today, considering that we are too late
in the Recommendation process; or
2) Reimplement the resolution to 103 (i.e. s/THE/AN/).
I have a preference for option 2) above and consider that this is an
editorial change only. However, I think we should first investigate
whether this change is likely to (severely) impact current
implementations. I don't think so, but at the same time I don't want to
take the risk of delaying publication.
I apologize for raising this issue so late in the Recommendation process.
Pls remove xmlp-comments of any follow-up discussions.
